aFe Twisted Steel Headers - GM Silverado/Sierra 1500 14-16

• Constructed out of 16-gauge, 1-3/4" mandrel-bent stainless steel tubing for unrestricted flow
• 4-to-1 mitered merge collectors eliminates flow-block turbulence seen on formed collectors
• Optimized tube lengths improve flow and performance
• 100% hand MIG-welded construction ensures optimal strength and durability
• Potential for up to +18 horsepower and +26 lbs. x ft. of torque when combined with aFe's y-pipe (P/N 48-44004)

These headers retain your stock catalytic converters and are a direct bolt-on installation which requires no cutting or drilling to provide a hassle-free installation.

4-to-1 Mitered Merge collectors decrease turbulence and increases exhaust velocity. The result is increased horsepower, torque and improved throttle response.

A thick, 1-piece flanges prevent warpage to ensure a leak-free seal over the life of the vehicle.

Tube lengths are optimized for true pulse control technology which improves flow and performance.

Pair with aFe's MACH Force-Xp Y-Pipe for even better flow-through for additional performance, horsepower and fuel economy. (P/N: 48-44004)
